openvswitch: Fix unsafe attribute parsing in output_userspace()

Browse source

commit 6beb6835c1 upstream.

This patch replaces the manual Netlink attribute iteration in
output_userspace() with nla_for_each_nested(), which ensures that only
well-formed attributes are processed.

Fixes: ccb1352e76 ("net: Add Open vSwitch kernel components.")
